Mixed red/green compound pads in Avids?

Picked up some spare pads for my Avid discs. EBC, one set of red, one of green. What about putting them that way on install? One of each in each caliper. Anyone done this?
I've only used standard Avid pads, and Kool Stops before. Thought I'd give the EBC pads a try.

You beat me to the question on this. I was talking about brake wear and squeal at my LBS and the EBC pads were brought up. The tech mentioned that he's sometimes installed a mixed set like that and has had some good success. His advice is usually good but I'd like some other opinions.
Has anyone done this? The idea is intriguing.

FWIW, I run the XT disc set and have been using shimano's pads. I go through several rear pad sets a year.

the kool stops haven't been as good. not bad, just not as good. they seem to fade more, and seem a bit less powerful - as in, i am needing to use more pull at the lever than before. didn't change anything else on the brakes, and yes, this was after plenty of wearing in. they seem to be crumbling, for lack of a better word, at the edges of the pad material. wearing faster than my avid pads did, as well.

thanks for the advice. i'll try the reds in front and see how they feel with green in back, then maybe swap for a few rides to compare.
